Some Keystones or abilities may grant you charges of Aether Flux, raw magical energy held in your Aether Core that you can send to Aethertech Devices to recharge them or empower them above their normal functions.
The Channel Aether ability, granted by all Keystones that grant ranks of the Aether Core ability, allows you to use 1 Minor Action to gain +1 charge of Aether Flux.
As a Free Action, you can expend any number of charges of Aether Flux to reload an Aethertech Device that is not loaded, with each charge spent counting as one use of the Reload action.
Aether Flux lasts for 1 minute before it dissipates. Your Aether Core can only hold 2 charges of it at once; if you generate any more than that, the excess charges are lost. This maximum can be increased via the Aether Capacitor ability granted by some Keystones.
